Influence of Foliar Application of Nutrients on Yield and Yield Attributes of Black Gram (Vigna mungo L.)

The present experiment was laid out at research farm of R.A.K. College of Agriculture, Sehore (M.P.) during Kharif season of 2022. The experiment was laid out in a randomized complete block design with 8 treatments and each treatment replicated three times. The Blackgram (cv. Pratap -1) was sowing with a seed rate of 15 kg ha-1 and with a spacing of 30 cm x 10 cm. The recommended dose of chemical fertilizer viz. 20:40:20 kg ha-1 N: P2O5: K2O, respectively was applied to the crop. Results revealed that foliar spray application of nutrient shows significant effect on yield and yield attributes. Treatment T7 (2% Spray of DAP + 0.5% Spray of ZnSO4 at pre-flowering and pod initiation stage) found higher for yield and yield attributes i.e. number of pods/plant (13.67), number of seeds/pods (6.15), seed index (4.76 g), seed yield/plant (2.21 g), seed yield/plot (836 g), seed yield/ha (786 kg), straw yield (1730 kg/ha), biological yield (2516 kg/ha), harvest index (31.21 %). While, minimum values found with T1 (Water spray at pre-flowering stage and pod initiation stage).
